Microspheres are an important material group with increased uses in mechanical, civil and environmental engineering. The microspheres with polyurethane as the wall material and dimethyl silicone oil as the core material were successfully prepared by interfacial polymerization method, which was incorporated into epoxy resin to enhance the damping properties. The new material was characterized by scanning electron microscopy and infrared spectroscopy. Results show that the microspheres had good sphericity and smooth surface. Dynamic mechanical thermal analysis showed that the incorporation of microspheres can elevate the damping performance of the epoxy resin.
